Even if they're going innawoods, you don't teleport there. Just bring cash instead of water, it's a lot lighter, buy some from a convenience store on your way out. If society collapses to the point money has no value compared to water, you've got a lot more problems than an ill-equipped bugout bag.

In fact, later in the article they even say to bring cash. Are you preparing to storm out of the house in a romance movie "Ah! I'm going to my sister's! Harrumph!" or are you preparing for nuclear winter?

And... a copy of your house deed? Just put that shit in a safe deposit box in a major bank far away from you. Again, if that winds up being a problem to retrieve due to societal collapse, but is immediately needed... Then there's bigger problems than your bugout bag.

An apocalypse bugout bag should contain water filtration, iodine tablets, a metal sleeping bag, and lots of firepower. The rest falls into place from there. A runaway bag should contain money... And you're pretty much good, that's about it.

Beyond this, you're better off not making a bag at all, just go for actual fortification of your existing life. Northern USA and central Canada, you're more likely to be facing being snowed-in for several days without power, than needing to flee anything in any immediate sense. Build for your local disasters.
